Turkish troops relieved
the garrison at Suleyman Shah's mausoleum - a tiny enclave of Turkey
where the forefather of the Ottoman empire is buried, the prime minister
says.
Sources say a large convoy, including tanks, passed through
Kobane, the city which Syrian Kurdish fighters retook last month from
Islamic State.The sources say the Turkish operation was co-ordinated with the Kurds.
One soldier is reported to died accidentally during the operation.
The border city of Kobane lies about 35km (20 miles) from the tomb of Suleyman Shah on the Euphrates River.
PM Ahmet Davutoglu tweeted that the remains of Suleyman Shah would now be moved to a different area of Syria under Turkish military control.
He is expected to make a full statement on the operation later on Sunday.
The tomb has been permanently guarded by a contingent of about 40 soldiers, who rotate periodically. The site is part of Turkish territory, according to a treaty signed in 1921.
The Turkish convoy was believed to be larger and more heavily armed than usual because of recent heavy fighting between the Kurdish militia and Syrian rebel groups against IS militants.
Since driving IS out of Kobane in January, the Kurdish Popular Protection Units (YPG) and rebels have taken a number of surrounding villages.
They are now said to be only 25km from Tal Abyad - the strategically important border town east of Kobane that is used by IS militants to cross into Turkey.
Islamic State has seized larges swathes in Syria and Iraq, proclaiming a caliphate.
